Abstract

A method of installing an off-shore tidal hydroelectric turbine generator is described. The method provides for a number of safety features, ensuring that all components are safe to handle during the installation operation, and also ensuring that the turbine will not start spinning during the installation operation.

Description

FIELD OF THE INVENTION[0001]This invention relates to a method of safely installing a sub sea tidal hydroelectric turbine generator.BACKGROUND OF THE INVENTION[0002]The increased interest in environmental awareness, and a reluctance to rely on non-renewable sources of energy, has led to greater usage of renewable energy systems, e.g. solar power, wind power, thermal power, and tidal power. The latter involves the installation of turbine generators in an area of tidal flow, and converts the energy of the tides into electrical power.[0003]With reference to FIG. 1, a direct-drive shaftless permanent magnet hydroelectric turbine generator is described in PCT Application No. PCT / EP2007 / 006258. The generator 10 comprises a ring-shaped stator 12 and a rotor 14, the stator 12 having a plurality of coils (not shown) located about the circumference of the stator 12. The rotor 14 comprises an inner rim 16, which defines an open centre. The rotor 14 further comprises an array of generally radia...
